Palaeocurrents and Depositional Setting in the Banganapalle Formation, Kurnool Sub-Basin, Cuddapah Basin, Andhra Pradesh

Palaeocurrents of the diamondiferous Banganapalle Formation show convergence towards Nandyal depression in the Kurnool Sub-basin. Localised depocentres, separated by E-W trending ridges, are identified near Kurnool, Paniam, Uppalapadu and Proddatur. These ridges pass through Gani, Banganapalle and Gandikota and have influenced sediment dispersal pattern in the Banganapalle Formation. Provenance for the Banganapalle Formation was mainly the intrabasinal tract occupied by lower Cuddapah sediments, igneous intrusives and the basement located to the west. Deposition commenced in an alluvial environment followed by intertidal setting.
